l `Application filed January 15, 1894- Srial No. 496,977. (No model.)

o all whom t may concern I Se it known that I, RICHARD G. BAILEY, a citizen of the United States, residing in the c1ty and county of San Francisco, State of California, have invented an Improvement in Fountain Marking-Brushes; and I hereby declare the following to be a full, clear, and exact description of the same. j t

My invention relates to a novel fountain and marking brush.`

It consists in certain details of construction whichwill be more fully explainedby referenceto theaccompanyingdrawings,inwhich- Figure l, is a side elevation partially broken away, ofV a fountain marking brush embodying my invention. .Fig 2.is a view of the g lower end of the valve and the stern by which the deviceis prevented from clogging. Fig. 3.1s a longitudin al'vertical section of my devlee.`

The object of my invention isto provide a markingbrush with a fountain attachment by which a proper supply of marking iluid is conveyed to the brush, and ameans by which the material is prevented from becoming clogged within the passages, and a means for attaching any ordinary brush and replacing the latter whenever necessary. t

A is a tubular shank or handle which may have a screw cap at B, or be permanently closed if preferred. At the lower end of this shank is a cross barD which allows sufficient space on each side of it for the passage of the marking iiuid or substance with which the handle isto be filled. If the upper end of the handle is permanently closed these spaces are of sufficient size to allow the handle to be filled from this end and the discharge takes place in the same `manner when thehandle has been reversed. From the center of the bar D, a stem C projects a short distance, and this stem has its lower end drawn down so as to form a conical valve and a flattened blade or plate C` which projects a short dis-` tance beyond the end of the valve.

E is abrush-holder. This brush-holder has its upper end screw-threaded and adapted to fit upon the lower threaded end of the handle A upon which it is screwed, and by which it is retained in place. The interior of this holder E is made conical, as shown at E', and the lowerconical valve end of the stem C closes against the inner part `of the cone E', when the part E is screwed upon the handle A until the cone of the part C is seated. This will close the central passage which is made through" the coneE and prevent any escape of the marking fluid when the device is not in use.'

The iiattened blade C extends below the cone of the stem C and into the narrow passage through the valve seat E of the holder E.`

hold the brush in place, While leaving a suliii j cient passage for the liquid to flow down` through the brush-holder and chamber and thence down the sides of the handle.

I is an exterior case made conical in shape having the'upperiend provided with slots in the form of a bayonet joint, to t over corresponding pins upon the exterior of the brushholder E, or it may be screw-threaded or otherwise secured thereto. This cone tapers, so that at the lower end there is just sufficient room for the brush .I to project through and be exposedbeyond the end of the cone.

Kus an exterior closed conical cap which is adapted to t over the cone I and the brush, and to close the whole device and keep it clean when not in use.

Whenthe device is to be used for marking purposes, the protecting cap K being removed, the brush-holder E is given a slight turn which unscrews it a littlefrom t the end of the handle A. 4This raises the conical valve at the end of the sternO from the interior conical seat E so as to allow the fluid to iiow through the opening in the conical seat E and into the chamber around the brush. Substances which are used for marking purposes usually contain a considerable quantity .of solid matter which will soon dry, and would ordinarily choke the passage through the cone E, `so that when the valve is opened no flow would take place. This difficulty is obviated IOO by the flattened blade C which forms an eX- tension below the conical valve and which, when the holder E is turned so as to unscrew it from the stem A, is rotated within the passage, thus cleaning out any accumulation of sediment or solid matter and providing for a free iow of the marking substance which then Iiows down into the larger chamber G, thence around the flattened end of the brush handle and down within the cone I, being eventuallydistributed to the exterior of the brush J, the supply being controlled by the amount of opening which is given to the valve C. By this construction two important advantages are gained, irst, I insure the cleaning out of the passage so that the'marking substance will always pass to the brush; and, secondly,I am enabled to replace the brush at any time and to use any ordinary cheap form of brush which can be obtained in the market.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a marking brush, the combination of a hollow handle adapted to contain the marking substance having a cap at one end and having its opposite end provided with a cross bar, a stein projecting from said bar having a valve at one end provided with a flattened extension, a brush holder threaded upon the handle portion having a seat for the valve and a passage for the marking substance through which said extension projects so as to leave a passage upon each side of the flattened extension, said brush holder having a chamber communicating with the passage and adapted to receive a brush having a flattened handle whereby the marking substance is permitted to flow from said chamber along .the sides ot' the brush handle to the marking from the lower end of the handle having a conical valve face at its lower end adapted to fit the seat in the brush-holder, and a fiattened plate extending therefrom into the passage through lthe seat in the holder, whereby the latter is cleared of sediment when the brush-holder is partially rotated and the marking fluid is allowed to ow down around the outside of the brush-handle, a hollow cone secured to the exterior of the brushholder and converging so that the small end of the cone has an opening through which the brush extends and by which the latter is supplied, substantially as herein described.

h In witness whereof I have hereunto set my and.
